I just installed a speed indicator thru the hull. I drilled the hole and used 3M 5200 sealant in black. I cleaned the surfaces with acetone and isopropyl alcohol. I also did a test set up with the plug with two old pieces of wood-I cannot break them apart. It did take several days to cure.
This will be a depth transducer for a Garmin. I like the wax ring idea a lot. It looks like the best place to locate it is on the center line of the hull at the aft end of the V berth.
